Teeth whitening is the procedure of wiping away the discoloration of teeth using chemical bleaching agents without damaging teeth.
The Methods of Teeth Whitening
In-Office Whitening is the method of bleaching in a clinical environment under a dentist’s care with the support of a light source. The bleaching agent is highly concentrated. As concentration is higher, whitening is faster. The process is brief. It takes generally one session to complete whitening, it might be 2 sessions in some cases. A session lasts between 30 and 45 minutes.
In-House Whitening is a method which is applied through private transparent whitening trays prepared by the dentist. The bleaching agent is less concentrated. It is applied every night for a week and the process is longer as the concentration is lower. Whitening tray must be worn for 8 hours if it is to be applied during daytime. It must be worn for 4 hours if it is to be applied during nighttime. It is recommended to apply it during nighttime as saliva flow is less in the night. Besides, it does not affect your daily activities if it is applied during nighttime.
In-Office Whitening is much faster. Moreover, sensitivity has almost come to an end thanks to high technology devices.
